Potential energy in molecules one model for the potential

Question

Please find the right solution of the given Problem

Problem- Potential Energy in Molecules One model for the potential energy of a two-atom molecule, where the atoms are separated by a distance r, is U(r) = Uo [(ro / r)16 - (ro / r)⁹] where r0 = 0.90 nm and U0 = 5.7 eV. Note: 1 eV = 1.6 x 10-19 J. You can use SI units, but CAPA will also accept these units that will simplify your calculations: [Force] = eV/nm [Energy] = eV [distance] = nm.

Part 1- What is the distance between the atoms when the molecule is in stable equilibrium? req = 1pts Tries 0/15

Part 2- If the distance between the atoms increases from equilibrium by r1 = 0.30 nm, then what is the force from one atom on the other associated with this potential energy? (Enter your answer as positive if they repel each other, and negative if they attract.) Fr(req+r1) = 1pts Tries 0/15 The atoms are oscillating back and forth.

Part3- The maximum separation of the atoms is r2 = 2.0 nm. What is the kinetic energy of the atoms when they are separated by the equilibrium distance? K(req) =

I want assist to calculate the distance between the atoms.
